Yeah, I bought a bunch of these buck voltage regulators several years ago thinking I could modify them. But, that turned out to be very difficult as I was unable to get any schematic diagrams for them. Still have them around here somewhere.
I know Jordan kind of stepped out awhile ago and he had, or at least he said that his employee was handling all of the purchases. I miss him as I would email him with questions and he always responded with the answers I needed. Things haven't been the same there for awhile.
Sure, I can let one go. Send me a PM and we'll get into the particulars there. Most of these measured around 190 mW after setup. None actually went to 200 mW and certainly not over. Just let me know if you are still interested.
We had a member here that lived in Australia who had all his lasers that he built confiscated. I think it was because he would post photos of each one and described their optical power especially. Don't know what ever became of him there. He might have been arrested, I just don't know.
Mine are not large beams at all. All of mine are small tight beams....even the 1300 mW one is. I remember trying to photograph the high power one and getting burned by passing in front of it to get a better camera shot. But the 240 mW one is tight as well. in fact, all my 532 nm DPSS lasers are...
The point is that handheld laser pointers aren't allowed to be imported or exported by mail into or out of Australia if they are a megawatt in power which we know is not at all true for that country. They have very strict laws against mailing even far lower power lasers pointers there.
Whoever put this out there had no understanding of power as defined in watts, miliwatts and megawatts. It is hilarious that they actually spelled out megawatts instead of just leaving it as MW. That, at least, could have been argued to be a typographical error.
I still have some 12 mm modules that are up to 200 mW in output power. Got them back when these were ubiquitous and the divers are adjustable. I could let one go for $40 plus shipping if you are interested. If you are just let me know. Otherwise good luck in your search.
I know you like to collect unusual wavelengths, but this one seems to not be that rare to me. Why did you want this one over others that are more rare? I used to have a really great relationship with techhood and got many unusual diodes from them, but this one doesn't seem that unusual.
These C mount diodes have been available for a long time. I wonder how this seller just came into possession of them now. I suppose he could of had them for years in his stock trying only now to move them.
I used a Pioneer laser disc player's tube and supply to build a 632.8 nm laser that I used in 1980 to make holograms with. That was my first laser and made quite a few reflection holograms. Gave it to my daughter years ago and it broke after falling out of her closet. ;)
